Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627034, here are decompositions:

7 + 31627027 = 31627034
67 + 31626967 = 31627034
151 + 31626883 = 31627034
193 + 31626841 = 31627034
367 + 31626667 = 31627034
463 + 31626571 = 31627034
487 + 31626547 = 31627034
541 + 31626493 = 31627034

Showing the first eight; more decompositions exist.
